Every single one of them. If I remember correctly there are about 6
million grass blades on the total target heightfield area. At that
density of grass. The render time was about 8 minutes. Mostly parsing.
It really is a brute force method. One WIP had about 11E6 blades and I
was shutting down programs as the memory usage climbed.
The target could be anything. Here is a link to one I made in reply to a
friend who sent me a sarky cartoon.

Crand!
Crand? I like to think of myself as an animator. I never use crand. ;-)
The "look" is very dependant on the closeness of the view.
I'm going to try to plant flowers to make an image from a poster, next.
